Islamism 'threat' greater than Nazism: SD leader

Acting Sweden Democrat leader Mattias Karlsson has said Islamism is "a greater threat than Nazism", sparking a strong response from Jewish and Muslim communities as the world marks 70 years since the liberation of Nazi concentration camps.

Mattias Karlsson, who is in charge of the Sweden Democrats for the foreseeable future after the party's leader Jimmie Åkesson announced on Tuesday that he was extending his sick leave, described Nazism as "terrible" in an interview with Swedish broadcaster SVT on Tuesday.

But he added that he felt the threat from Islamism today was "perhaps greater than from Nazism".
